GAMLLOWS-VFRAME FOR PORTABLE DRIVING MECHANISMS.

SPECIFICATION forming part of Letters Patent No. 279,650, dated June 19, 1883.

Application filed I ebruary 17, 1883. (No model.)

I?) roll whom it may concern Be it known that I, WARREN T. KELLoec, of Oohoes, in the county of Albany and State of New York, have invented certain new and useful Improvements in the Construction of Gallows-Frames for Portable Driving Mechanism, of which the following is a specification.

My invention relates .to improvements in the construction of frames for containing portable devices for imparting motion to rotary fan-blowers and other revolving machinery; and the object of my invention is to provide for such purposes a fire-proof frame combining the maximum of strength with the minimum of Weight. i

To this end my invention consists in c011- structing said frames entirely of wroughtiron, of which the greater part is in the form of angle-iron bars, the several parts being constructed and combined in the manner herein shown and described.

In the accon'ipanying drawings, which form part of this specification, and to which reference is made herein, Figure 1 is a perspective view of my improved gallows-frame containing a driving-wheel and shaft; Fig. 2, a side elevation; Fig. 3, a front elevation, and Fig. 4 a horizontal section at the line-X X.

As illustrated in the drawings, the gallowsframe consists of an upright frame, A, transverse tie-bar B, foot-pieces (7', and fore and aft braces D.

The upright frame A is made of a single bar of angle-iron, which is bent to form the arched top a, and, as shown in the drawings, which illustrate my preferred construction of said frame, the angle-iron is bentso that one of its flanges will form a wide perimetric face for said frame.

Thetransverse tie-bar B is secured to the lower ends of the two vertical limbs of the frame A, and so that it will rigidly hold the said limbs at the required distance apart.

A foot-piece, C, is secured to the bottom end of each limb of the frame A, the said foot 5 pieces being arranged in. parallel lines at right angles to the width of the frame, and so as to extend equally to the front and rear of said frame, and thereby forming alarge and firm base for maintaining the gallows-frame in its erect position. Said foot-pieces are preferably'inade of angle-iron, and are secured to the frame A by means of rivets or screw-bolts.'

The two fore and aft braces, D, are made of flat iron in the form of an. inverted V. The said braces are fixed at opposite sides of the frame A, and each has its apex secured to the adjoining side of said frame, while its two ends are secured to opposite ends of the footpiece 0 at the correspondent side of the frame. By means of said braces the frame A is maintained in position perpemlicularly to the foot-pieces. A driving-shaft, E, arranged to revolve in the bearings e, secured to the front of the frame A, carries a driving-wheel, F, from which motion can be taken for anyrequired purpose, and said wheel may optionally be either acogwheel or a pulley, as the occasion may require. A;rotatory motion can be imparted to the shaft E by means of a hand-crank, a friction clutch operated bya lever, or by any other of the Well-known appliances used for such purposes.

I claim as my invention-- As an improved article of manufacture, a

wrought-iron gallows-frame for portable driving mechanisms, consisting of the upright frame A, made of a single bar of angle-iron bent to form the arched top a, as herein described, transverse tie-bar B, foot-pieces G, and fore and aft braces D, the whole being constructed and combined as herein specified.
